[xsl] Re: Re: msxsl:script and selectSingleNode problem

["Dimitre Novatchev" <dnovatchev@xxxxxxxxx>]

I cannot reproduce your problem.

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
 xmlns:msxsl="urn:schemas-microsoft-com:xslt"
 xmlns:scrdt="urn:reval-com:scripts:datatypes">

 <xsl:output omit-xml-declaration="yes"/>

  <xsl:template match="data">
    <xsl:call-template name="callInit">
      <xsl:with-param name="itemNode" select="items"/>
    </xsl:call-template>
  </xsl:template>
  <xsl:template name="callInit">
    <xsl:param name="itemNode"/>
    <xsl:value-of select="scrdt:init($itemNode)"/>
  </xsl:template>
  <msxsl:script language="JScript" implements-prefix="scrdt"><![CDATA[
     function init(itemNode)
     {
     if( !itemNode.length) return "";

     var val = itemNode.item(0).selectSingleNode('book');

     //var val = itemNode.item(0).firstChild;

     if(val!=null)
     return val.text;

     return "Error";
     }

]]></msxsl:script>
</xsl:stylesheet>

when applied on your source.xml (corrected to be well-formed!):

<data>
  <items>
    <book>My book Title</book>
    <pencil>My pencil length</pencil>
    <pen>My pen color</pen>
  </items>
</data>


Produces the wanted result:

My book Title


both with MSXML4 and MSXML3.
